Introduction
In this article, we will discuss a super technique to fix the blinking error in any mini split air conditioner brand. We will specifically focus on Fujitsu mini split air conditioners and understand the error codes and motherboard editions. We will also explore various troubleshooting steps to identify and fix the serial communication error that causes blinking lights on the indoor unit display. Whether it's a faulty relay, problematic motherboard, or faulty communication wire, we'll provide solutions to help you resolve the issue and restore the functionality of your air conditioner.
Understanding the Error Code
Before diving into the troubleshooting steps, it's essential to understand the error code displayed by the blinking lights on the indoor unit. Different editions of Fujitsu motherboards have distinct blinking code patterns. We'll decipher these patterns and help you interpret the error code accurately to proceed with the troubleshooting process.
Identifying the Edition of the Motherboard
To effectively diagnose and fix the serial communication error, it's crucial to identify the edition of the motherboard. By examining the numbers and inscriptions on the outdoor and indoor motherboards, we can determine which edition of the control board is installed. This information will guide us in troubleshooting and finding the appropriate solutions for the specific motherboard edition.
Checking the Flow of Electricity
One of the primary factors that contribute to the serial communication error is the interruption or lack of electricity flow. We'll guide you through the process of checking whether electricity is passing through the outdoor and indoor motherboards. If there's a disruption in the electricity flow, it can cause blinking problems or errors in the air conditioner.
Checking the Switching Relay
The switching relay plays a crucial role in controlling the electricity flow between the indoor and outdoor motherboards. We'll demonstrate how to inspect the relay and listen for its switching sound to determine its functionality. A faulty relay can prevent the proper transmission of electrical output, which may lead to a serial communication error in the unit.
Checking the Communication between Indoor and Outdoor Motherboards
The communication between the indoor and outdoor motherboards is vital for the smooth operation of the air conditioner. We'll show you how to examine the communication circuit and ensure there are no issues or malfunctions. If the communication is disrupted or faulty, it can be a sign of a problematic outdoor or indoor motherboard. We'll provide remedies for both scenarios.
Problematic Outdoor Motherboard or Communication Circuit
If the communication circuit in the outdoor motherboard is not working or the motherboard itself is faulty, it can lead to a serial communication error. We'll guide you through the necessary steps to diagnose and address these issues effectively. By troubleshooting and identifying the problematic component, you can take appropriate action to resolve the error.
Faulty Communication Wire
Another common cause of the serial communication error is a faulty communication wire. We'll explain how humidity can affect the silver wire, causing it to deteriorate and hinder the proper transfer of communication data between the indoor and outdoor units. However, if copper wire is installed, the super technique we're about to reveal can effectively overcome this issue.
The Super Technique to Fix the Problem
We'll introduce you to a super technique that can fix the serial communication error in your air conditioner without the need to install a new wire. By checking the continuity of the wires and making a simple wire exchange between the line and neutral terminals, you can solve the problem. This technique has proven successful in resolving communication issues in various air conditioner brands, not just Fujitsu.
Conclusion
In conclusion, troubleshooting a serial communication error in a mini split air conditioner requires a systematic approach. By understanding the error codes, identifying motherboard editions, checking the flow of electricity, inspecting the switching relay, and examining the communication between indoor and outdoor motherboards, you can effectively diagnose and resolve the issue. Additionally, the super technique we've shared can eliminate the need for installing new wires and provide a solution in most cases.
